“I spent way too long on the user side and basically forgot to think about the supply side (the celebrities themselves) until I was halfway through.” The rest of the author's notes on Product Manager interview at Meta, Onsite - Product Sense / Strategy round, covers how they worked through the question, what the panel pushed back on, and what they would do differently.

“I had a decent story but fumbled the structure a bit.” The rest of the author's notes on Software Engineer interview at Meta, Onsite - Behavioral / Leadership round, covers how they worked through the question, what the panel pushed back on, and what they would do differently.

“The core idea isn't hard: build a prefix sum array over sorted cities, generate a random number in [0, total_population), binary search for it.” The rest of the author's notes on Machine Learning Engineer interview at Meta, Technical Phone Screen round, covers how they worked through the question, what the panel pushed back on, and what they would do differently.

“My first instinct was to sort both strings and diff them, which would've been fine but they nudged me toward O(n).” The rest of the author's notes on Software Engineer interview at Meta, Technical Phone Screen round, covers how they worked through the question, what the panel pushed back on, and what they would do differently.

“I knew the algorithm but explaining the 'why' behind each step while coding at the same time was harder than expected.” The rest of the author's notes on Software Engineer interview at Meta, Technical Phone Screen round, covers how they worked through the question, what the panel pushed back on, and what they would do differently.

“I went straight to DAU/MAU and they let me talk for a bit before nudging me toward something more nuanced.” The rest of the author's notes on Data Scientist interview at Meta, Onsite - Product Sense / Strategy round, covers how they worked through the question, what the panel pushed back on, and what they would do differently.

“The core bug is a priority issue in the rendering logic, path symbols are applied after start/end symbols so they clobber them.” The rest of the author's notes on Software Engineer interview at Meta, Technical Phone Screen round, covers how they worked through the question, what the panel pushed back on, and what they would do differently.

“I went straight to neighborhoods and local events, which felt obvious in retrospect.” The rest of the author's notes on Product Manager interview at Meta, Onsite - Product Sense / Strategy round, covers how they worked through the question, what the panel pushed back on, and what they would do differently.

“I started with BFS since tracking depth per level feels natural there, but then they pushed on doing it in one pass for both views simultaneously.” The rest of the author's notes on Software Engineer interview at Meta, Onsite - Coding / Algorithms round, covers how they worked through the question, what the panel pushed back on, and what they would do differently.
